I have recently purchased a Cisco ATA 191 for use with an analog phone system I need for a specific use case. I can successfully provision the ATA, but after a successful provisioning the device never shows as online, and does not work with any analog phone that I try.
My guess is I have to configure something on the ATA itself regarding TLS connection settings, but I can’t find any documentation anywhere to guide me through this process. The only thread I can find on the RingCentral community points to a help article that now redirects to a 404 page.
Can anyone provide any help?
